Casual WHM-IIC-10 "Zap and woosh" (2xcLPL, 3xcERML, 3xLRM10, AMS, TC1, cXL350) + alt (2xcLRM20)

Decent vomit laser build that combines 3xLRM10 (best LRM spread with almost best alpha strike) for indirect fire support.

This build is heat stable with LRMs only, so play it as a normal vomit laser build with the added feature of indirect fire support / suppression while cooling down. Stick with your team, fire at any target of opportunity and you will be fine.
Due to the high heat generated when alpha striking, do not fire LRMs with direct LoS after the first alpha strike: most of the times you will waste your heat.

About skills, I would max almost anything in firepower, coolrun and sensors.

ALT: hotter LRM20 version
